本节内容来自 LLVM Weekly 第 548 期， Alex Bradbury 大哥持续稳定输出。

• 恭喜 Alex Bradbury！ Last week I was honoured and delighted to be recognised with the Software Contributor Award by the RISC-V International Board of Directors.

• 收藏： Additional videos were uploaded to the EuroLLVM 2024 recordings playlist.

• 宋教授！ Fangrui Song wrote up integrated assembler improvements in LLVM 19, which resulted in measurable performance gains.

• LLVM 19 要来了： Tobias Hieta shared the proposed LLVM 19 release schedule, with the branch occurring on 23rd July and the final release planned for 3rd September.

本周推荐：《星月之下：游思土耳其》

作者： 西闪、 西门媚

推荐： 小编1号

在初筛的时候带上这本书的原因，是因为纸质书裁剪得比较小，装订也舒服，图片也多，适合在为了钱而出差的时候看看别人为了钱之外的意义去一些自己肯定不会去的地方写感受。

每个故事段落都不长，适合碎片的时间。内容深度也并不深刻，并非需要挺直了腰背表情严肃的文字。

还行。
